Eddie Hearn, promoter for heavyweight contender Dillian Whyte, admits his fighter is taking a very dangerous risk by immediately jumping into a rematch with Alexander Povetkin.

Last month at Matchroom's Fight Camp in Brentwood, Povetkin scored a sensational knockout of Whyte in the fifth round.

Whyte had dropped Povetkin twice in the fourth, before the Russian veteran clipped him with a massive uppercut in the fifth for a brutal knockout.

Coming in to that fight, Whyte was the WBC's interim-champion and mandatory challenger to the full beltholder Tyson Fury.

All of that went down the drain with the unexpected loss.

Whyte has exercised an immediate rematch clause, with the second contest being finalized for November 21.

Hearn admits that all of the pressure in the rematch is sitting on the shoulders of Whyte.

"All of a sudden, the pressure is not just on trying to become the mandatory and fight Tyson Fury, this is the pressure of his [Whyte's] career on November 21," said Hearn to Sky Sports. "Controlling the fight, a brutal knockout, and all of a sudden like that, his career spins on its head.

"He's hugely motivated to put this right, but it's extremely dangerous and of course, moving into the rematch, just 13 weeks after the first fight is very, very dangerous. But Dillian Whyte wouldn't have it any other way.

"I think it is terminal for his world title chances - and that's obviously the ultimate aim for Dillian Whyte. I think he knows the pressures. He was deeply disappointed with getting knocked out from an amazing bit of skill from Alexander Povetkin, and he's got to put that right.

"Povetkin and his team ready to go. They don't see a problem. They've knocked him out once, they think they're going to do it again in November. A very confident Alexander Povetkin, and all of a sudden, all of the pressure lies on the shoulders of Dillian Whyte."
